Cultivating pedagogy: exploring the influence of intentional time spent outdoors on pre-service and novice educators’ teaching practice and philosophy development
(2025)The objective of this study was to examine how intentional time spent outdoors impacts pre-service and novice educators’ teaching practice and the development of their teaching philosophy. Current literature surrounding ... -
A special case of the range of invariant problem for AF type actions of Z₂
(2025)Elliott and Su gave a classification of inductive Limit type Z2 actions on AF algebras using a K-theoretic invariant. In this paper, we consider the range of invariant problem, and give a sufficient condition for an ... -
Functionalized lignin derivatives for flame retardant, thermal insulation, and coating applications
(2025)Lignin, a highly branched and heterogeneous biopolymer composed of phenolic units, is a key structural component of plant cell walls, providing mechanical strength, water resistance, and protection against microbial ... -
Effect of lignin content on the performance grade and stability of asphalt binders used in Thunder Bay
(2025)The design roads relies solely on bitumen as a binding agent because it provides superior adhesive properties and waterproofing capabilities. The main source of bitumen production from crude oil oil refining results in ... -
Upward book embeddings of DAGs: constraint-based methods and embeddability analysis
(2025)The k-page upward book embedding (kUBE) problem is a fundamental challenge in graph theory with applications in circuit layout, scheduling, and hierarchical visualization. Despite its relevance, the problem—particularly ... -
Tools from above: evaluating drone-borne aerial remote sensing systems for archaeological site and feature identification
(2025)Archaeological investigations are rapidly changing due to developing digital technologies. They affect data collection, processing, interpretation, and analysis, but have spawned new approaches to archaeological ... -
Predator-prey interactions under thermal pressure
(2025)Ectotherms' ecological performance is directly linked to their thermal environment, many of which are warming due to climate change. If predator and prey thermal niches differ, warming may impact the intensity of ... -
A process design for the purification of carbon contaminated with Cu-Bi alloy from catalytic methane decomposition
(2025)Low-carbon hydrogen production by catalytic methane decomposition (𝐶𝐻4→𝐻2(𝑔)+𝐶(𝑠)) has demonstrated potential to significantly decarbonize industrial sectors. Previous research has proposed carrying out the reaction ... -
Characterization of the Hewitt Lake and Leta Arm groups, Indin Lake Greenstone Belt, Northwest Territories
(2025)Exposures of the Leta Arm (LA) group and southwestern Hewitt Lake (HL) group volcanic rocks in the northeast-trending 2670-2629 Ma Indin Lake Supracrustal Belt (ILSB) of the western Slave Craton were studied to understand ... -
The short-term effects of dry cupping the lumbar paraspinal muscles in individuals with non-specific low back pain: a single-blind randomized trial
(2025)Introduction: Non-specific low back pain (NSLBP) is a leading cause of global disability, affecting millions of individuals and imposing significant personal and societal burdens. Current treatments (chiropractic or ... -
Tactile texture classification on uneven surfaces using a neural network soft voting ensemble
(2025)With the growing capabilities of intelligent robots in object recognition and manipulation, the ability to sense and interpret physical contact through touch has become a crucial component to enabling effective interaction ... -
Examining First Nations dementia perspectives and wholistic relational supports for culturally safe risk reduction, assessment, and post-diagnosis care in Northwestern Ontario
(2025)In Canada, the incidence of dementia among First Nations, Métis, and Inuit (FNMI) populations is projected to increase by 273% by 2050, in comparison to 187% among non-FNMI populations. While Canada’s dementia strategy ... -
Computational investigations of vortex dynamics and dynamic stall of pitching airfoils at high Reynolds number
(2025)This study employs high-fidelity Detached Eddy Simulations (DES) and modal decompositions to elucidate dynamic stall mechanisms on a pitching NACA 0018 airfoil at 𝑅𝑒 = 160000. Proper Orthogonal Decomposition (POD) isolates ... -
Variables associated with performance on a cognitive screening measure and cognitive remediation training outcome in the acute phase of Major Depressive Disorder
(2025)Major Depressive Disorder (MDD) is associated with cognitive deficits, particularly in the domains of attention, memory, and executive functioning (EF). Previous research has demonstrated that residual cognitive deficits ... -
Patterns of genotype-environment association in the eastern North American yellow birch (Betula alleghaniensis Britt.)
(2025)Understanding how genomic adaptation shapes species’ responses to climate change is essential for developing climate-resilient forests, as shifting conditions increasingly drive range shifts and maladaptation. This study ... -
Adding JoyPopTM: evaluating an e-mental health app as a complementary tool alongside treatment for youth using the RE-AIM Framework
(2025)Given the growing rates of mental health concerns and the need for accessible support tools among youth (ages 12-24), mobile health (mHealth) apps offer an avenue to support youth. Little research has determined where ... -
Feature extraction enhances model performance
(2025)Deep learning has emerged as a prominent approach in traditional machine learning paradigms due to its superior capability for deep-level feature extraction. This, in turn, demonstrates that the efficiency, depth, and ... -
Linking landscape structure to woodland caribou density using non-invasive spatial capture-recapture
(2025)Assessing how landscape composition and anthropogenic disturbance influence spatial variation in abundance is essential for effective conservation planning in threatened species. For woodland caribou (Rangifer tarandus ... -
Listening to perspectives of Animbiigoo Zaagi’igan Anishinaabek Elders, hunters, and youth on environmental contaminants and their impacts
(2025)Traditional foods are integral to the Animbiigoo Zaagi’igan Anishinaabek (AZA) First Nation in Northwestern Ontario. More than simply sustenance, they also play an integral role in the community’s culture, health and ... -
